[HTC Inspire 4G] gtg465x:
I get great data speeds here (3.8 down, 1.3 up). I'm using our stock radio. Never even unlocked to switch radios because the stock one has worked great on every ROM I've tried.

This is my first time trying MIUI. These are my first impressions:

Pros:

1) The depth of customization by the MIUI dev team is amazing. It's a completely different experience.

2) Many elements have really nicely done, professional looking graphics.

3) The notification pulldown is very unique and functional. Pull down on the left side for notifications and pull down on the right side for a ton of toggles. You can also switch and kill apps from within the notification pulldown.

4) Nicely done messaging app. The iPhone-like pop-ups when you receive a text are pretty cool, but can be disabled if you don't like them.

5) Excellent camera app with a clean interface. Supports tap to focus.

6) Nice looking gallery app with some convenient features. Has an option to rescan the SD card. The crop box is set to the correct size (selects the entire picture) when setting wallpaper.

7) Cool music app. Browse by folders. Auto download album art and song lyrics.

8) Nice dialer. Looks up contacts as you dial.

9) Nice file explorer. Has an FTP server function.

10) Cool app called Monitor. Shows total call time and number of text messages. Shows your data and wifi usage by day, week, and month and you can customize alerts. Also has a built in firewall so you can prevent apps from connecting on 3G, etc.

11) Built in notes app. Useful.

12) Excellent theme manager app. Allows you to change and browse online themes, wallpapers, ringtones, icons, fonts, boot animations, etc.

Cons:

1) Not quite as stable as CM7 and Sense ROMs and feels somewhat beta (because it is). I get a force close after every boot with LauncherPro. Sometimes I get a force close when trying to edit certain contacts. Had to turn off compatibility mode for the xda app to get it to display right. I've seen gray on white text in a couple places and it's hard to read. Some strings, especially in Settings, could use slightly better translations. It's unclear what a few settings do. All of these issues will probably be cleared up eventually.

2) Not as smooth as CM7. Launching applications and scrolling between screens with LauncherPro is a touch less smooth than CM7. All settings menus are pretty laggy. I assume that will be fixed sooner or later. The gallery app is somewhat laggy. Notification pulldown seems slightly less smooth... probably because it's white and just has a lot more stuff on it.

3) Not crazy about the stock launcher and icons. They're a little too iPhone-like for my tastes, but that's personal preference.

4) No option for music player controls in the notification pulldown.

5) Album art looks blurry and ugly on the stock lockscreen.

6) Facebook contacts sync is a little wonky. Wanted to sync all of my Facebook friends with numbers despite selecting sync only existing contacts.

7) No built it weather app right now. Download the beta MIUI weather app on the first page, pull AOSP app, or use Beautiful Widgets, etc. Not a big deal.

8) Don't see any options to set the CPU speed and governor. Need to install SetCPU. Not a big deal.

9) Don't really like the included ringtones, but the theme manager can take care of that. Not a big deal.

Hope that helps some of you understand where this ROM stands currently.
